Design Concepts for Using the Switch

As your network users compete for network bandwidth, it takes longer to send and receive data. When
you configure your network, consider the bandwidth required by your network users and the relative
priority of the network applications that they use.

network to increase the bandwidth available to your network users.
Table 1-1 Increasing Network Performance
Network Demands
Too many users on a single network
segment and a growing number of
users accessing the Internet
Increased power of new PCs,
•
workstations, and servers
High bandwidth demand from
•
networked applications (such as
e-mail with large attached files)
and from bandwidth-intensive
applications (such as
multimedia)
Bandwidth alone is not the only consideration when designing your network. As your network traffic
profiles evolve, consider providing network services that can support applications for voice and data
integration, multimedia integration, application prioritization, and security.

Suggested Design Methods
Create smaller network segments so that fewer users share the bandwidth, and use
•
VLANs and IP subnets to place the network resources in the same logical network
as the users who access those resources most.
Use full-duplex operation between the switch and its connected workstations.
•
Connect global resources—such as servers and routers to which the network users
•
require equal access—directly to the high-speed switch ports so that they have
their own high-speed segment.
Use the EtherChannel feature between the switch and its connected servers and
•
routers.
